Analyzing the power from the outlet


I've been reading threads on the various methods of power cleaning -- filters, regenerators, dedicated lines, etc. But I don't see a thread that explains a systematic way of evaluating the condition of the power at the outlet. Is there a thread or a link that instructs on how to analyze the power for noise, voltage consistency, etc from the point of view of an audiophile?

Great inputs from Ralph (Atmasphere), as usual.

Gbart, thanks also for calling attention to the papers presenting the many measurements. I haven't taken the time to read most of them yet, but FWIW I would suggest to those who do read them that whatever conclusions are reached by the author be carefully scrutinized, and not just accepted at face value. I say that because not long ago, in connection with a thread here on fuse directionality, I did thoroughly review Part 7 of those papers, relating to fuses. My comments on it were presented here.

Tboooe - I am probably oversimplifying things, but if your regenerator is really generation new clean power, what would the purpose of a dedicated line be? Almost seems like it would be similar to pretreating dirty water going into water purification plant that produced perfectly clean H2O.
mceljo, I dont pretend to be an expert on electrical matters but your example makes sense to me. My only thought on why getting a dedicated line + an AC regenerator would offer benefits is that by supplying cleaner power and grounding, the regenerator does not have to work as hard? Perhaps there is noise that it cannot completely filter out?
You didn't pay for a "filter", that would be a power conditioner. You paid for a product advertised to regenerate the power. It seems that if you believe what they say then you should take them at their word.
Rodman99999, thanks for the links to PowerVar products. I enjoyed watching Part2 & Part3 & found the info useful.
